Runs the LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS unless the user had predefined them in the environment.
The script must support ‘–cflags’ and ‘–libs’ args. If MINIMUM-VERSION is specified, the script must also support the ‘–version’ arg. If the ‘–with-library-[exec-]prefix’ arguments to ./configure are given, it must also support ‘–prefix’ and ‘–exec-prefix’. Prefereable use CONFIG-SCRIPTS as config script, CFLAGS-ARG instead of ‘–cflags‘ and LIBS-ARG instead of ‘–libs‘, if given.
The SED-EXPR-EXTRACTOR parameter representes the expression used in sed to extract the version number. Use it if your ’foo-config –version’ dumps something like ’Foo library v1.0.0 (alfa)’ instead of ’1.0.0’.
The macro respects LIBRARY_CONFIG, LIBRARY_CFLAGS and LIBRARY_LIBS variables. If the first one is defined, it specifies the name of the config script to use. If the latter two are defined, the script is not ran at all and their values are used instead (if only one of them is defined, the empty value of the remaining one is still used).
would run ‘foo-config –version’ and check that it is at least 1.0.0, if successful the following variables would be defined and substituted:
FOO_CFLAGS to `foo-config --cflags` FOO_LIBS to `foo-config --libs`
AX_PATH_GENERIC([Bar],,,[ AC_MSG_ERROR([Cannot find Bar library]) ])
would check for bar-config program, defining and substituting the following variables:
BAR_CFLAGS to `bar-config --cflags` BAR_LIBS to `bar-config --libs`
would link with a static version of baz library even if ‘baz-config –libs‘ returns just "-lbaz" that would normally result in using the shared library.
This macro is a rearranged version of AC_PATH_GENERIC from Angus Lees.
